23 Claims.

My invention relates to building constructions.

It is the object of my invention to provide a self-supporting, load-carrying, concrete reenforcement that serves the muitiplepurpose of a joist carrying a load, a concrete supporting memher, a floor support and a ceilingsupport.

It is my object to provide a building construc tion of poured concrete withoutshores, in which the load is carried from wall to wall by the same fabricated truss that positions the ceiling and floor members and any concrete associated therewith thereby saving the time of erecting shores and forms and waiting for their removal.

It is a further object of my invention to provide either permanent or detachable soiilt mem bers which hold in position metal fillers and arches or tile ceiling liners or tile filler blocks.

It is a further object to provide removable sofiits which can be quickly detached and, when removed, leave a ceiling finish that is smooth and ready for the ceiling decorations.

It is my further object to provide a construction which is adaptable to either corrugated ceilings or smooth ceilings.

It is a further object to provide structural joist members with detachable soflits and permanent soffits so that variations in length of ceilings or distance between walls may be accommodated with a standard construction.

Referring to the drawings:

Figure 1 is a side elevation of the fabricated self-sustained reenforcing unit;

Figure 2 is an end view thereof;

Figure 3 is a section of a removablef steel core formed construction;

Figure 4 is a section of similar construction employing a terra cotta ceiling andthe perma nent steel core form;

Figure 5 is a section showing the use of terra cotta tile block filler Figure 6 is a section through a solid concrete flat slab construction;

Figure 7 is a longitudinal section of the reenforcement and cross section of steel I-beams r showing the method of supporting the joist on the steel Ibeam;

Figure 8 is a similar view where a reenforced concrete beam is employed;

Figure 9 is a similar view showing a support on a masonry wall; Figure 10 is a perspective View of' the metal portions of my invention arranged for pouring; Figure 11 is a perspective of the temperature expansion rod;

the assembly of I-beams, concrete metal cores and terra cotta ceiling; v Figure'13 is a section on the line 13-13- of Figure 1.

Referring to the drawings in detail, the selfa sustained, fabricated, reenforcing beam is formed of deformed bars. The bottom bar is designated 1 which extends fromend to end of the structure. The top baris designated2. Bars 1 and 2are secured together by welding to them the diagonal rod 7. Thus, one-half of the reenforcing unit is manufactured. Likewise the bottom bar 3 being bent a predetermined distance from each end with inclined portions 5 and horizontally extending portions 6, which latter portions are welded to the top bars. Vertical web rods 8 are placed in position and welded at the bottom to the bottom bar 3 and at the top to the top bar 4, thus completing the other half of the unit. It will be notedthat the point of departure from the bottom and the point of arrival of the bar 3 at the top, where the diagonal portion 5 is used for this purpose, are points where the vertical web rods 8 are located. 50

A similar vertical web rod 8 is located at the center of the span. Thus, two fabricated members composing the truss are welded together at intervals. i

Suitable spacers are provided between'the bottom bars 1 and 3 and the top bars. 2 and 4 to give. space between them for adequate joining of the concrete and to provide a space for receiving the temperature expansion rods 91;. The shear plates 9 are secured in the space between the top bars 2 and 4. This shear plate 9 is pro- .vided with the angle members 10. The bottom flangesof the angle members 1O form a; horizontal base to which is secured the permanent soiiit 11. The bottom bar 1 is welded adjacent its end to the vertical web of the angle 10.

The permanent soiflt 11 is welded as indicated having upturned ears 12. The detachable soflit 14. is adapted to cooperate with the permanent soilit so that there will be'a continuous spac provided, as hereinafter described.

Arch-shaped steel forms 14c "are mounted within the upturned flanges 15 of the, soffits 14 for supporting them in position. The soffits themselves are suspended by the interlocking brackets 16, the upper ends of which are formed in hooks libeneath which are laterally extending fingers 18. The lower ends of these brackets 16 are also formed with hooks 19 which 'extend outwardly through slots in the soffits, De-

tachable wires 20 are inserted in the hooks 19 beneath the soffits to hold the soflits in position. These hook members 19 may be single or double,

. as indicated.

be noted that the soffits may be either inverted or right side up depending upon the use to bev made of them.

In the form shown in Figure 4 the ceiling plates of tile designated 28 are provided with. slots 29 for receiving the lower edges of the steel forms 14a, a portion-of the tile extending at 30 between the grooves 29 directly over the soflits thusrforming the wedge shaped projection into the concrete designated 31. This column of concrete constitutes'a part of the joist that rests upon the walls 32.

The fabricated, self-sustained reinforcing unit may rest. directly on the concrete wall 32 with it reenforcing 33 as indicated in Figure 8 or it may rest upon the I-beam 34; in the wall 32 by reason of the bracket 35 which'is welded between the rods 2 and 4 at the extreme ends of the self-sustained, fabricated member. 3'7 designates the spacer member between the upper bars and 38 the spacer member between the lower bars.

. Operation The two units consisting of the top and bottom bars 1 and 2 and the top and bottom bars 3 and 4 are assembled in welded condition. The end plates Qand permanent soffits 11 are installed. Such members are spaced apart with their 'ends resting upon the walls 32. The forms 14a and the soffits 14 are placed in position together with the tile members either 28 or 24 or the filler member 26. The concrete is then poured without the use of shores. After the concrete is poured the sofiits may be removed by pulling the pins20 andthe steel forms 14a may be removed if the arrangement shown in Figure 3Yis used.

If the arrangement shown in Figure 4- is used, then the sofiits may be removed but the forms 14a will remain in place. p

In the form shown in Figure 5 the sofrlts will remain if desired, otherwise, they may be removed. r

The same istrue of Figure 6.

Thus, with the same standard construction spaced with the temperature spacing bars 9a the entire floor can bepoured resting upon the walls without the use of shores producing a smooth ceiling or a corrugated ceiling or a sound proof ceiling as desired depending upon the precise arrangement of the interchangeable parts. The truss structure enables the load to be carried while, at the same time, provides the reenspecification. They are exactly in position ver' tically. being. positioned by the temperature present type of reenforcing material is absent because the positioning of the present loadsupportingparts is positive and mathematically exact; it does not depend upon the judgment of common labor or of foreman as to the placing of the units.

The temperature expansion rods are arranged from twelve to eighteen inches apart. The result is a concrete joist 31 and a floor slab 36 integral with one another.

The core forms and sofiits can be used over and over again. If it is desired to plaster the ceiling, therods 20 which are mounted in the hooks 19, after the soffits have been removed, are utilizedas a means of sustaining the wire lath upon which the plaster is placed.

Thus, air is allowed to circulate behind the metal lath throughout its length and prevents discoloring'of the plaster because there is air in one place and solid material in another.

The forms 14a are preferably made from sixto fourteen inches in depth and one, two or three feet, in length; the dimensions may be varied to suit the demands of the construction.

When the sofiits. are removed the hooks 19 are taken oh if they are not to be used for suspending the metal lath. Then the ceiling is plastered in the usual manner.

It will be understood that I desire to comprehend within my invention such modifications as may be necessary to adapt it to varying con ditions and uses.
